Spanner wrench



Patented Aug. 4, 1931 UNITED STATES- JOSEPH G. COR-DELL, OF GLENSHAW, PENNSYLVANIA SPANNER WRENCH Application filed October 19, 1929. Serial 110,400,892.

My invention relates to spanner wrenches which are adapted to remove bearing adjusting nuts from the rear axle housing of an automobile. Y 7

One object of my invention is to provide an inexpensive adjustable spanner wrench which is adapted to remove bearing adjusting nuts of greatly difierent sizes.

Another object of my invention is to prolovide a wrench in which the axle serves as the fulcrum for loosening a bearing adjustin nut.

Still another object of my invention is to provide a spanner wrench which will be simple and economical of construction and positive and reliable in operation.

Briefly speaking my invention consists in 1 roviding a lever with an arcuate portion which will fit over an axle or shaft and having a bar pivotally mounted at one end of the lever for fitting in one of the slotsor grooves in a bearing adjusting nut. The axle serves as a fulcrum about which the lever actuates the nut. I

For a better understanding of my invention reference may be made to the accompanying drawings.

Figure I is a view in side elevation of a spanner .wrench constructed in accordance with'my invention.- 1

Figure II is a plan view of the same wrench. Figure III is a vertical section through 'a rear wheel bearing showing the manner in which the wrench is employed'to remove a bearing adjusting nut. I

Figure IV is a view in side elevation of the bearing illustrated in Fig. III.

Figure V is a view in side elevation of a modified form of spanner wrench constructed in accordance Withmy invention.

And Figure VI is a plan view of the spanner wrench illustrated in Figure V.

Referring particularly to Figures I and II of the drawings, the spanner wrench 1 comprises a lever 2 having an arcuate portion 8 and an end 4 in which there are a plurality of bolt holes 5. A bar 6 is pivotally mounted upon the end 4 of the wrench 1 by means of a 50 bolt 7. The bar 6 is provided with a -plural-' ity of bolt holes 5 correspondingto-rthose I the end 4. i if The object of the three bolt holes 5"in' both the end 4 of the wrench 1 and the bar, 6 is to provide adjusting means for varying the 15- distance of the bar6 from the arcuate portion 3 of the wrench 1 and also to'vary the'distance of'the bolt 17 from the end of the bar 6.

The manner 'inwhich my wrench is employed. may be best understood by referring to Figure III and IV of the drawings wherein a stationaryhousing 11 ofan' automobile is shown provided with a flange 12 for supporting the brake bands. A n axle 13 is rotatably mounted in saidhousing 11 by means of a threaded bearing adjusting nut 14. i v

The bearing adjusting nut 14 amoun ed]: in the correspondingly threaded annular flange 15 which is an integral part of the flange 12. When the bearing adjusting nut 7 I 14 has been positioned 'inthe flange .15 for sometime it may become bent or rusted and '.f is diflicult to re movefl 5 I The bearing i'adj uste with an innerfannular ring 16 which is posi-" tionedo'directly'"onthe axle 13. A plurality of roller bearings are rotatably mounted between the adjusting nut .14 and'its inner annular ng nut 14 is Provided.

with pluralit y of grooves 17 to i t 'QO itsremoval. y I j The bearing adjusting nut 14 is removed by placingthe arcuateportion 3 ofwrench 1 on the axle "13 and inserting the end of the bar 6 in OIiQQfth grooves 17 ofthe nut 14. The operator keeps one hand on the bar 6 to maintain it positioned in the groove 17 and actuates the lever o2,ofthe' wrench 1 with the other hand; I

The holes 5 in the end4of the wrench 1 and the bar 6 permit the bar 6 to be adjusted so as to provide for different sized bearing adj usting nuts 14.

'Referring to the modified form of my id ventio n illustrated in Figures 5' and 6 of the drawings, the wrench 19 is provided with a V shaped bend 20which makes it adapted to fit over axlesjof difierent diameters. At

the end 21 ofthe wrench 19, a lug 22- is provided. This lug 22 is substantially perpendicular to the plane in which the remainder of the wrench 19 lies. The lug 22 is provided in place of the bar 6 illustrated in Figures LIV, inclusive, of the drawings.

The advantage of the modified form of the wrench is that it may be made of a single piece of wrought iron and is adapted to fit on a widevarietyrof; axles;

It is apparent th'ateither Wrench 1 or 19" 10 may be used to screw the nut 14 into the annular flange 15 ofithe-lmusinglh What I claim as my invention is 1.
